セラミックナチュア グアバリーフ

Tossed a couple of these leaves in the tank a week ago and the water's been noticeably clearer, plus the shrimp seem to love grazing on them. The antibacterial angle is what sold me, and so far no signs of any worms or infections.

My shrimp have been much more active since I added one of these guava leaves to the tank, and the water seems clearer too. The antibacterial effect against worms is exactly what I needed for my freshwater setup.

Works well for my shrimp tank, noticed less fungal issues after a few weeks. The leaves are a bit brittle and break apart when submerged, but the antibacterial effect makes up for it.
